The AT90S8515 is an "old-style" (one of the very first) AVR microcontrollers, and it does not have the SPM instruction or the ability to self-program its own flash memory, which is necessary for a bootloader-based environment like Arduino to operate properly.  Basically, you can't use an 90S8515 without a specific "device programmer" module, and one of those is comparable in price to a full Arduino (even the cheaper versions will likely cost as much as an Arduino clone.)

There is a newer AVR that is similar to the 90s8515 (ATmega8515), but except for pins it has less capabilities than even the older Arduino chips (like the ATmega8)  Arduino variants like Sanguino (http://sanguino.cc) that use a 40-pin chip seem to have settled on the ATmega644.

what is device programmer
A piece of hardware that goes between your computer and a micrcontroller chip or board that allows programs to be loaded into the chip.  Typically these will support many different microcontroller chips, each with many options, and they're aimed at EE and CS engineers.  They'll consequently be much more complicated to use than an Arduino.
Examples include The Atmel STK-500 and the Adafruit USBtinyISP

Yes, that should work for programming a 90s8515.

In THEORY, it should be possible to slightly modify the arduino environment so that it can download to other chips via an external programmer (anything supported by the AVRdude utility, I guess, by modifying hardware/boards.txt, plus the core libraries.)  In reality, if you can do that then you don't have much need for the arduino environment in the first place...

Is it that difficult to buy an Arduino platform? You can get pre-programmed chips for around $5. As it appears that you are still a noob I would buy a full Arduino platform which is between $20 and $30. It  will save you a bunch of headaches.

Did you check the distributors in Asia. Even if you buy in the USA, air shipping to Asia can be fairly cheap.
